Pin Description
Serial Clock (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge
clock data out of each device.
Serial Data (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be
wire-ORed with any number of other open-drain or open-collector devices.
Device/Page Addresses (A
total of four 4K devices to be addressed on a single bus system. Pin 1 is a no connect and can be connected to ground
